Can’t Access Email Address; Password forgotten.

I have a pretty old email address I could do with getting in to as it is attatched to an account for another site that I wish to access. The problem is a have forgotten the password (due to the age of the address). I've tried recovering it through the usual channels, but for some reason I can't get the answer to my security question (I don't see why this is because there's only so many ways you can spell a cats name...), and nor do I hold enough information regarding emails sent from the account to recover it by filling out the form.

I was wondering if maybe the email no longer exists, does hotmail/microsoft delete them after some time? And if so can I check some how?

Also is there any other hope I may have of recovering the address? I was hoping to find a number or email address to contact Microsoft support at but there doesn't seem to be one...?

Any help would be hugely appreciated, thanks.
